Our tests reveal that adding hydrogen in the form of HHO into an engine will not increase the fuel mileage on all cars and trucks. It will however reduce emissions to almost zero.

As a rule, if your miles per gallon in town is 5-6 mpg less than on the highway, a Fuel Genie System will improve mileage. If mpg on the highway is more that 6 mpg in town chances are this system will not improve your mileage but it will still reduce emissions to almost zero.
